Which of the following is not a function that can be performed using the Braze API?

The function of tracking a user's actions in an app is fundamental to Braze's capabilities, allowing businesses to understand user behavior and enhance engagement through targeted messaging. This involves setting up event tracking to analyze user interactions, which directly informs marketing strategies.

On the other hand, migrating data from external sources, performing ongoing data collection, and exporting user data are all integral parts of Braze's functionality. The ability to migrate data ensures that businesses can integrate Braze effectively with their existing data infrastructure. Ongoing data collection allows for real-time insights and analytics, enabling continual optimization of marketing efforts. Lastly, exporting user data from Braze is crucial for businesses that need to analyze their user base outside of the Braze environment or for reporting purposes.

Thus, while tracking user actions is a core capability of Braze, the other functions relate more to data manipulation and integration, which further enhances the platform's value for marketing teams.
